Question

我正在使用活动模型序列化程序来序列化用户。

在我的卖家控制器中，我有，

def index
   seller = User.all.where(catagories: "seller")
   render json: seller, status: :ok,  status: :ok
end

UserSerializer课程看起来像这样。

  attributes :id, :name, :email, :phone_number, :verified
  has_many :products
  has_one :address`

输出也很公平。

{
    "users": [
        {
            "id": 1,
            "name": "Craig Crist",
            "email": "adena_kiehn@greenfelder.com",
            "phone_number": "876.862.8760 x0096",
            "verified": true,
            "products": [
                {
                    "id": 1,
                    "name": "Direct Performance Transmitter",
                    "price": 1000,
                    "warranty": false,
                    "discount": 50,
                    "description": "Vel doloribus distinctio nihil rerum libero. Reprehenderit ratione cumque porro nesciunt. Id recusandae aut vel voluptatem aperiam hic deleniti voluptas."
                }
            ],
            "address": {
                "id": 1,
                "latitude": 41.022921,
                "longitude": -118.064638782714,
                "street_name": "Beattystr.",
                "city": "Hermannport"
            }
        }

但我需要将响应封装在名为data的密钥中。

data : {
        "users": [
            {
                "id": 1,
                "name": "Craig Crist",
                "email": "adena_kiehn@greenfelder.com",
                "phone_number": "876.862.8760 x0096",
                "verified": true,
                "products": [
                    {
                        "id": 1,
                        "name": "Direct Performance Transmitter",
                        "price": 1000,
                        "warranty": false,
                        "discount": 50,
                        "description": "Vel doloribus distinctio nihil rerum libero. Reprehenderit ratione cumque porro nesciunt. Id recusandae aut vel voluptatem aperiam hic deleniti voluptas."
                    }
                ],
                "address": {
                    "id": 1,
                    "latitude": 41.022921,
                    "longitude": -118.064638782714,
                    "street_name": "Beattystr.",
                    "city": "Hermannport"
                }
            }

我可以通过将data键的数据包装在如下所示的哈希中来实现所以我的索引方法看起来像这样。

 def index
   seller = User.all.where(catagories: "seller")
   render json:  { data: { user: seller } },  status: :ok
end

但在执行此操作后，关系不会在json中呈现。

{
    "data": {
        "user": [
            {
                "id": 1,
                "name": "Craig Crist",
                "email": "adena_kiehn@greenfelder.com",
                "phone_number": "876.862.8760 x0096",
                "verified": true,
                "avatar": "https://robohash.org/voluptatemsintnon.png?size=300x300",
                "badge": 3,
                "catagories": "seller",
                "rating": 1,
                "created_at": "2017-06-25T10:31:39.575Z",
                "updated_at": "2017-06-25T10:31:39.575Z"
            }

我也使用gem 'api-pagination'对这个数组进行分页，但是

用户封装在数据中后，api-pagination也会停止工作。

如何实现所需的输出并将其分页？

以下是两种方法：

render json: User.all, adapter: :json_api

或

# in config/am_serializer.rb
ActiveModelSerializers.config.adapter = :json_api

# in controller
render json: User.all

现在响应将呈现为

{
  "data": {
    "id": "1",
    "type": "profile",
    "attributes": {
      "name": "Julia"
    }
  }
}

json_api适配器旨在符合此处定义的规范http://jsonapi.org/

有用的链接：
https://github.com/rails-api/active_model_serializers/blob/0-10-stable/docs/general/serializers.md#other

但这会将响应格式更改为jsonapi。所有api的响应格式都不同。客户端应用程序不遵循jsonapi标准

试试这个，它应该有用

render json: {data: ActiveModelSerializers::SerializableResource.new(User.all)}

默认适配器为json而不是json_api

如何将API响应封装在＆＃34;数据＆＃34;键和分页？
